"If there are some who compromise their real opinions, or the chance of reaching truth, for the sake of gain, there are far more who shrink from giving their intelligence free play, for the sake of keeping undisturbed certain luxurious spiritual sensibilities. This choice of emotional gratification before truth and upright dealing with one's own understanding, creates a character that is certainly far less unlovely than those who sacrifice their intellectual integrity to more material convenience. The moral flaw is less palpable and less gross. Yet here too there is the stain of intellectual improbity, and it is perhaps all the more mischievous for being partly hidden under the mien of spiritual exaltation."
